4 most powerful transformers

I've been reading the IDW series lately and they feature a lot of big baddies. My question is who are the most powerful Autobots, Decepticons, and who are the most powerful from both sides? Its my new thread so I guess I have to go first.

Autobots
1. Fortress Maximus - No surprises here, I've always thought of him as being bigger than Metroplex and thus more powerful.
2. Metroplex - Of course he has to come in second considering he is a freaking city bot
3. The Beast - a combiner made from the Dinobots?! Do I have to explain how epic he is? Even though he looks silly.........
4. Omega Supreme - Subject powerful, arguments unnecessary.

Decepticons
1. Trypticon - A dinosaur AND a citycon? need I say anymore?
2. Monstructor - "All that lives BURNS for Monstructor"
3. Thunderwing - he nearly wiped out all transformers in the universe. twice I might add. That has to count for something
4. Sixshot - He is a one man assault force. He's wiped out entire planets. He has six different modes. I like him...

I would like to keep this G1, but who knows maybe some people think Rampage or some other guy would stand a chance against these guys.

I think that power isn't always a case of who can bench press the most weight. We often see that the characters that are in the most powerful positions are the ones with the intelligence and drive to take power rather than follow others. Skill also seems to play a part in power as a character like Master Splinter from TMNT can defeat characters three times his size.

So I'd say the two most powerful are Prime and Megatron since they both always end up as the leaders and neither one will really stop until they accomplish their goals. Heck in most of the series even dieing hasn't been enough to stop these two.

After that it gets a bit tricky as to who might fill out the other slots if they ever came up with a Transformers version of something like Deadliest Warrior.
